Direct electric freight rail is not speculative technology. It already operates across enormous railway systems, moves very heavy freight and works in difficult climates. The interesting North American question is therefore not whether electric freight rail can work, but where catenary should go first, where batteries or dual-mode locomotives make … [continued]

Hydrogen cost forecasts often borrow one of the clean-energy transition’s most useful empirical tools: the experience curve. If a technology has historically fallen by a given percentage in cost every time cumulative deployment doubles, analysts can estimate how many doublings lie ahead and compound the learning rate into a future … [continued]
